H. B. FAY, OF NEW YORK, N. Y.

STOVE.

Specification of Letters Patent No. 26,756, dated January 10, 1860.

T 0 all whom it may concern:

Be it known that I, H. B. FAY, of the city, county, and State of NewYork, have invented a new and Improved Stove; and I do hereby declarethat the following is a full, clear, and exact description of the same,reference being had to the annexed drawings, making a part of thisspecification, in which Figure 1, is a side sectional View of myinvention, taken in the line :0, m, Fig. 3. Fig. 2, is a transversevertical section of ditto, taken in the line y, y, Fig. 3. Fig. 3, is ahorizontal section of ditto taken in the line a, a, Fig. 1.

Similar letters of reference indicate corresponding parts in the severalfigures.

This invention consists in combining a wood and coal-burning stove insuch a way that either kind of fuel, (wood or coal) may be used asdesired and the stove made to diffuse equally as much heat with eitherfuel as those stoves that are constructed especially for each.

To enable those skilled in the art to fully understand and construct myinvention I will proceed to describe it.

A, represents the body or case of the stove. This body or case may beconstructed of sheet metal and transversely of elliptical form, thisform would be preferable although other forms may be used. The body orcase is provided with a door a, at each end, and within the body or caseA, a firechamber B, is placed directly opposite one of the doors and inclose proximity to it. This fire-chamber is for coal and it may be ofcylindrical form and of a suitable diameter according to the size of thebody or case A. The bottom of the fire-chamber is provided with a grateG, arranged in any of the usual ways and directly below the grate C, isthe usual ash-chamber D.

The body or case A, is provided with a horizontal plate 6, which formsthe bottom of the wood fire-chamber. This fire-chamber comprises thewhole of the interior of the case A, that is not occupied by the coalfire-chamber B.' The bottom plate 6, is some distance above the bottom0, of the case A, and the space between them is occupied by theash-chamber D, of the coal firechamber, and a flue d, the lattercommunicating with the smoke pipe E, by a pipe 6, within the case A, andsaid flue also communicating with the interior of the case by a pipe 7,

.end.

Y as shown clearly in Fig. 2. The smoke pipe If a wood fire is desiredthe same is built on the plate 6, which, as before stated, forms thebottom of the wood fire-chamber. In kindling either fire the damper g,is opened in order to obtain a direct draft and when the fire is underway the damper g, is closed, and a circuitous draft obtained downthrough the pipe 7, through the flue (Z, and up through the pipe 6, intothe smoke pipe E, as indicated by the black arrows in Fig. 1. The directdraft is indicated by the red arrows in Fig. 1. The coal fire issupplied with air through the door 72), of the ashchamber, and the woodfire is supplied with air through a register 2', below its door a. Acurrent of air passes up through the tube A, and is heated by the fireeither by the coal or wood fire-chamber. This heated air mingles withthe inflammable gases in the upper part of the case A, and causes themto ignite. The air in passing through F, will be heated even when a woodfire is used, sufiiciently so to prevent its cooling down the fire ineither fire-chamber, of course it will be heated to a greater degreewhen a coal fire is used, but still the woodfire heat would answer forall practical purposes. By this invention therefore not only twodifferent kinds of fuel may be used in the same stove but the greatestamount of heat may be obtained from either kind used, as the inflammablegases generated or evolved by an imperfect combustion will be unitedwith warm oxygen at the upper part of case A, and will'be consumedwithout cooling the fire below.

This stove may be cheaply constructed not greatly exceeding an ordinarywood stove and the combination of a wood and coal stove is verydesirable. In extreme cold weather a coal fire of course is preferable,as it does not, as with wood, require frequent replenishing. In mildweather a wood fire is preferable as its heatis more readily controlledthan is the coal fire and more readily obtained. There are many timesalso when the chillonly requires to be taken off the room and this canbe'readily' done by the Wood fire Without overheating the room.

Having thus described my invention What I claim as new and desire tosecure by Letters Patent, is,

The arrangement of the coal fire-chamber B, Within the body or case A,the flue d, 10

and the ipes 6, f, communicating respectively' With the smoke pipe E,and the in terlorv of the case A, for the purpose specified.
